Filed De 7' 964 ii?? T) United States Patent 3,270,704 ANCHOR Stig Johan Bruno Ekberg, Hasselbyvagen 78, Spanga, Sweden Filed Dec. 7, 1964, Ser. No. 416,392 Claims priority, application Sweden, Dec. 9, 1963, 13,612/63 4 Claims. (Cl. 114-208) This invention relates to an anchor.

Various constructions of anchors having movable and adjustable fiukes are available in the market. Experience has proved, however, that these anchors are not always as eifective as desired. They are often likely to be dragged long ways along the ground with the fiukes failing to catch in the ground.

The object of this invention is to eliminate this disadvantage. I attain this object by a mechanism illustrated in the annexed drawing in which:

FIG. 1 is a front elevation of a preferred embodiment of the anchor with one of the fluke-s omitted, and FIG. 2 is a lateral elevation of the complete anchor with a pair or flukes located one on each side of the shank.

Referring to the drawing the lower end of the shank 1 of the anchor is provided with slots 2 and 3. Movably mounted in these slots are pins 4 and 5 which interconnect the flukes 6 and 7 which are located one on each side of the shank 1. The pin 4 is movable in the slot 2 which extends along the symmetry .axis of the shank. The other pin 5 is movable in the slot 3 which is provided nearest the lower end of the shank. The slot 3 has two branches located one on each side of the symmetry 3,270,704 Patented Sept. 6, 1966 axis of the shank. Each of the branches make an angle with said axis in the proximity thereof. This angle is obtuse as viewed from the upper end of the shank. Bower branches of the slot 3 are curved. As a result thereof the flukes are forced to make an angle with the ground with their points directed towards the ground if the anchor is dragged along the ground by applying a pull to the eye of the shank.

If desired, the flu-kes may be detachably mounted on the shanks such as by means of cotters or bolts, not shown.

What I claim is:

1. An anchor comprising a shank, a pair of movable flukes located one on each side of the. shank, the lower part of said shank having a first slot extending along the symmetry axis of the shank and a second slot located below said first slot and having two branches located one on each side of said symmetry axis, each of said branches making an angle with said axis in the proximity thereof, a first pin movable in said first slot, and a second pin movable in said second slot, said pins being rigidly connected to both flukes.

2. An anchor as set forth in claim 1 wherein said angle is obtuse as viewed from the top end of the shank.

3. An anchor as set forth in claim 1 wherein said branches are curved.

4. An anchor as set forth in claim 1 wherein said fiukes are detachably mounted on said shank.
